分页方法
复制代码 代码如下:
/// <summary>
///
/// </summary>
/// <typeparam name="T"></typeparam>
/// <param name="replist">控件ID</param>
/// <param name="DataSource">数据源</param>
/// <param name="IndexPage">当前页</param>
/// <param name="PageSize">每页数据条数</param>
/// <param name="PageParemart">页面搜索参数 like &a=a&b=b </param>
/// <returns></returns>
public static string ShowPage<T>(System.Web.UI.WebControls.Repeater replist, IQueryable<T> DataSource, int IndexPage, int PageSize, string PageParemart)
{
string rtnStr = "";
int sourceCount = DataSource.Count();
if (sourceCount == 0)//数据源无数据
{
rtnStr = string.Empty;
}
else
{
int yutemp = sourceCount % PageSize;
int pagecounts = (yutemp == 0) ? (sourceCount / PageSize) : (sourceCount / PageSize + 1);//总页数
rtnStr = " <div><div>页次：" + IndexPage + "页/" + pagecounts + "页，共" + sourceCount + "条记录</div> ";

页面调用
复制代码 代码如下:
private int PageSize = 10;
private int IndexPage = 1;
private string PageParemart = "";
private void Bind()
{
strwhere = "1=1 " + strwhere;
str2 = "1=1 " + str2;
var a = from b in datas.fav_Awards_User select b;
Label2.Text = common.PageFen.ShowPage(replist, a, this.IndexPage, this.PageSize, this.PageParemart);
if (Label2.Text == "")
{
Label1.Visible = true;
}
}
